I have been trying to get Windows OS Deployment to Macs using WDS working off and on for the past year or so but still haven't managed it. I have had no problems with getting Windows 8.1 to deploy, but 7 seems to fail each time.
I am using WDS integrated with SCCM, have tried using the built in GPT partition maps and also using diskpart scripts as detailed here Deploy Windows on Macs using MDT. by Guillaume Remy with no success. I have just tried installing OS X clean, then running Boot Camp assistant, then booting from SCCM Boot media. The Windows files copy to the partition then task sequence still fails. If I try to boot from the partition I receive the standard windows 'No Bootable device -- insert boot disk and press any key' message from the windows boot loader.
Has anyone managed to get this working, any advice would be gratefully received.
Thanks,
Mark
